Abstract: Concentrating devices, systems, and methods include those for separating fluids to be sensed (e.g., analytes, such as volatile organic compounds (VOCs) and/or other chemical substances) from other fluid (e.g., a carrier gas, air, etc.) of a fluid mixture received from a target area of a subject's anatomy (e.g., a subject's skin, a wound on a subject, etc.). In some cases, the concentration system may include a housing and a rotor positioned in a compartment of the housing. The housing may receive a fluid mixture in the compartment and rotation of the rotor relative to the housing may separate fluid to be sensed in the fluid mixture from other fluid of the fluid mixture.

Abstract: Detection devices, systems, and methods include those for detecting analytes (e.g., volatile organic compounds (VOCs) and/or other chemical substances) from a target area of a subject's anatomy (e.g., a subject's skin, a wound on a subject, etc.). In some cases, a detector may have a detecting component that includes an analyte sensitive material applied to a substrate. The detector may be used with a pump. The detector may include a hydrophobic, gas permeable material configured to limit liquid reaching the analyte sensitive material, while allowing analytes in gaseous fluid to reach the analyte sensitive material.

Abstract: Collection devices, systems, and methods include those for collecting volatile organic compounds (VOCs) and/or other chemical substances from a target area of a subject’s anatomy (e.g., a subject’s skin, a wound on a subject, etc.). In some cases, the collector may have a collection component including an adsorbent material. The collector may be used with a pump. The pump may be configured to draw a fluid flow containing one or more chemical substances from a target area on a subject’s anatomy through the collection component. The collection component may be configured to collect at least some of the chemical substances from the fluid flow as the flow passes through the collection component.

Abstract: A bucket associated with a machine is provided. The bucket includes an integrated RADAR system. The bucket also includes a first compartment provided at a first section of the bucket. The first compartment defining a cavity. A control module of the RADAR system is mounted within the cavity of the first compartment. The bucket further includes a second compartment provided at a second section of the bucket. The second section is opposite to the first section. A sensor module of the RADAR system is mounted within the second compartment. The sensor module is configured to scan and penetrate a ground surface proximate to the bucket. The bucket includes a channel extending between the first compartment and the second compartment. The channel is adapted to house wires that communicably couple the sensor module with the control module.

Abstract: In one embodiment, a wavefront sensor is combined with a slit lamp eye examination device so that real time aberration values of an eye being examined can be viewed during a slit lamp eye examination session.

Abstract: A wavefront sensor includes a light source configured to illuminate a subject eye, a detector, a first beam deflecting element configured to intercept a wavefront beam returned from a subject eye when the subject eye is illuminated by the light source and configured to direct a portion of the wavefront from the subject eye through an aperture toward the detector and a controller, coupled to the light source and the beam deflecting element, configured to control the beam deflecting element to deflect and project different portions of an annular ring portion of the wavefront from the subject eye through the aperture and further configured to pulse the light source at a firing rate to sample selected portions of the annular ring at the detector.

Abstract: One embodiment is a method for finding, calculating and electronically marking a reference axis for astigmatism correction/neutralization of a patient eye during a refractive surgery. The reference axis for astigmatism correction/neutralization can be determined intra-operatively based on one or more eye property measurements together with simultaneous recording a live eye image. The determined reference axis of astigmatism correction/neutralization can be updated and registered with one or more land mark(s) of the recorded eye image(s); and overlaid onto a live image of the eye. Another embodiment is a method of calculating and displaying in real time compensated refractive errors of the eye under operation with refractive components due to temporary surgically induced factors removed and refractive components due to surgeon-induced factors added.

Abstract: Example embodiments of a large dynamic range sequential wavefront sensor for vision correction or assessment procedures are disclosed. An example embodiment includes first and second optically coupled 4F relays and a variable focus lens disposed substantially at the image plane of the first 4F relay and the object plane of the second 4F relay.

Abstract: One embodiment disclosed is a compact wavefront sensor module to be attached to or integrated with an ophthalmic instrument for eye examination and/or vision correction procedures. The front lens for relaying the wavefront from the eye to a wavefront sampling plane is positioned at the optical input port of the wavefront sensor module. The front lens is shared by the wavefront sensor and the ophthalmic instrument, and the wavefront sensor module can be made very compact while still being able to cover a large eye wavefront measurement diopter range. Another embodiment disclosed is an ophthalmic device for measuring properties of a subject eye including an ophthalmic instrument integrated with the wavefront sensor module.
